So I bought a lifetime license on ebay for $20 and I was like alright and they mailed me the code on my ebay account within 30 minutes. So I tried downloading malwarebytes trial on malwarebytes website but the serial did not work so they gave me a download link to a malwarebytes corporate version 1.80 and according to the seller it still gets update and I just updated to the malwarebytes data base and it went through but the application is the old application that it used to look like back in 2015 or 14? I am just asking was it safe to install it because there is no way there going to offer a refund.
